Are Return Tickets Required for HKSAR -> China Travel?
 

As title, would a HKSAR (Resident with Right of Abode) need to show a return ticket to travel to China? The HKSAR residents have all other necessary travel documents (including travel visa) for entry, but not sure if a return ticket will be necessary as well.

Not if you have a visa, hrp, rp etc. Also note that walking across the border is pretty common; no tickets are required for that.
